More clothing items for your MP character would be nice and especially variety of cloths types,No more just winter cloths cause I want the option to have a muscle shirt/go shirtless/plain t-shirt/jean shorts/etc!!

One thing I'd doubt it'd happen But I think it'd be cool is having it be like Red Dead Redemption where you can select different types of characters&animals for transportation..But in this case you get to be choose from characters in this game and vehicles you'd want to have primary control of like you press a button and the vehicle comes to you(like Batman in Batman'89)
